Imaging apparatus, data processing method, and program

1. An imaging apparatus comprising: an orientation sensor that detects orientation representing the direction in which the imaging apparatus is oriented; a controller that produces data formed of a captured image and attribute information associated with the captured image and records the data in a recording section; and the recording section that stores a captured image and attribute information, wherein the controller records a series of entries in a memory, the series of entries relating orientation information calculated by successively receiving a value detected for each entry with the orientation sensor to a time stamp representing the time at which the detected value is inputted from the orientation sensor, extracts a selected plurality of entries from the series of entries with each one of the selected plurality of entries having time stamps close to the time at which the image was captured from the series of entries recorded in the memory, and calculates an orientation representing the direction in which the image was captured by using the selected plurality of extracted entries and wherein the controller extracts the selected plurality of entries having time stamps close to the time at which the image was captured from the series of entries recorded in the memory, reselects a small number of entries having intermediate values of orientation information of the extracted entries, and sets the average of the orientation information of the plurality of reselected entries as the orientation representing the direction in which the image was captured.

2. An imaging apparatus comprising: an orientation sensor that detects orientation representing the direction in which the imaging apparatus is oriented; a controller that produces data formed of a captured image and attribute information associated with the captured image and records the data in a recording section; and the recording section that stores a captured image and attribute information, wherein the controller successively records an entry in a memory, the entry relating orientation information calculated by successively receiving a value detected with the orientation sensor to a time stamp representing the time at which the detected value is inputted from the orientation sensor, extracts a plurality of entries having time stamps close to the time at which the image was captured from the entries recorded in the memory, and calculates orientation information representing the direction in which the image was captured by using a plurality of pieces of orientation information in the extracted entries, wherein the controller selects a single representative entry having a time stamp closest to the time at which the image was captured from the entries recorded in the memory, selects a specified number of near entries having time stamps close to the time stamp of the representative entry, sorts the plurality of entries formed of the representative entry and the near entries in increasing or decreasing order of magnitude of orientation information, and removes at least the greatest and smallest end entries from the sorted entries, averages the values of orientation information in the remaining intermediate entries, and sets the average as the orientation information representing the direction in which the image was captured.

3. The imaging apparatus according to claim 1 , wherein the controller acquires time at which each continuously captured image was captured, extracts the selected plurality of entries having time stamps close to the time at which each continuously captured image was captured from the entries recorded in the memory, and calculates orientation representing the direction in which each continuously captured image was captured by using the orientation information in the extracted entries.

4. The imaging apparatus according to claim 1 , wherein the controller extracts the selected plurality of entries having time stamps close to the time at which a central image of a panoramic image produced by combining a plurality of captured images was captured from the entries recorded in the memory and calculates orientation representing the direction in which the panoramic image was captured by using the orientation information in the extracted entries.

5. The imaging apparatus according to claim 4 , wherein the controller calculates the time at which the central image of the panoramic image was captured from the time at which an imaging start frame of the panoramic image was captured.
